I had sex last night (Sunday) and am taking to pill Monday, should it work or no?

(Sorry for the tmi) But I had sex about 4 in the morning on Sunday technically and I want to get the morning after pill and the soonest i can get it is on Monday or Tuesday. I won't get pregnant right??

The morning pill isnt something to rely on for protection against pregnancy. Never say to yourself, "well, it is okay to have unprotected now because I can always go get an emergency contraceptive pill" and think everything will be okay. These pills do not offer enough protection to rely on them. They are only about 80% effective, so that still gives you a 20% window to get pregnant. That doesnt sound too bad until you consider that you have about a 70-75% chance to get pregnant using nothing at all so emergency contraceptives only give you maybe 5-10% more protection but 10% is 10%. All it does is to hopefully delay ovulation long enough so that any sperm within you dies before an egg is released. If the egg was already released before you took the Pill, well your chances for getting pregnant are much higher and this pill isnt going to offer you any protection! It is very difficult to predict when you ovulate.

Apps provided on your smart phone or PC are not accurate and are only "guesstimates" at best. They are based on averages but very few women are average. Even dedicated charters have trouble predicting ovulation. Also consider that regular birth control pills when taken consistently and correctly can be 98-99.9% effective. You are much better off taking regular birth control pills if you think you may be sexually active. You are protected 24/7/365 when you take them properly so there are no worries! Make an appt at your local County clinic or Planned Parenthood or your personal gynecologist and get yourself on reliable birth control!
